Abstract

A voltage controlled LC-oscillator(LC-VCO) has been designed to cover a wide range of frequencies (2.0-4.1 GHz) using an area efficient and svvitchable multi-tap inductor and a capacitor bank. The multi-tap inductor provides a signilicant area advantage, and in spite of a degraded Q, provides an acceptable phase noise of-123 dl3c/Hz and-113 dl3c/Hz at an offset oft MHz at carrier frequencies of 2 and 4 GHz respectively. Implemented in a 0.13 pm CMOS technology, the oscillator occupies an active area of 0.095.onn2. With 69 % tuning range and a maximum./3-1.-co of about 360 MHz/V, it consumes 9-16 mW of power. It. can be used for cognitive radio and other wide-band and multi band RP applications.
